Ineed , i get like 4712, but its not an answer

So you will need to find the height, and we can do so by using the pythagorean theorem, which is . Using this formula, we can make the equation

Firstly, solve the exponents:

Next, subtract 225 on both sides:

Lastly, square root both sides, and your answer is h = 20.

Now that we got the height, we can solve for the volume, which is . Using this formula, we can form our equation to be

Firstly, solve the exponent:

Next, multiply 225 and 20/3, and your answer will be V = 1500π, or the third option.

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!
